ifconfig여러 네트워크 인터페이스가 나열되며 그 중 일부는 가상 인터페이스입니다.
어떤 프로세스가 어떤 네트워크 인터페이스를 사용하거나 수신하고 있는지 확인하는 방법은 무엇입니까? 감사해요.

ss -plntcp 포트의 프로세스를 나열 p하고 l바인딩된 IP 및 포트는 물론 관련 PID 및 파일 설명자를 표시합니다.nt
$ sudo ss -plnt | grep -E ':(22|8384)[^0-9]'
LISTEN 0 128 192.168.42.2:8384 0.0.0.0:* users:(("syncthing",pid=14565,fd=8))
LISTEN 0 128 0.0.0.0:22 0.0.0.0:* users:(("sshd",pid=6099,fd=3))
LISTEN 0 128 [::]:22 [::]:* users:(("sshd",pid=6099,fd=4))
이전 버전과 비교 netstat -plnt:
$ sudo netstat -plnt | grep -E ':(22|8384)[^0-9]'
